Clifford, Woodstock, 11]., assignor to Chicago Pottery Company, Chicago, 111., a corporation of Delaware Filed Apr. 9, 1963, Ser. No. 271,641 2 Claims. (Cl. 4252) This invention relates to toilet construction, and more particularly to an improved wall mounted toilet bowl.

Wall mounted toilet bowls are in widespread use and they are becoming more and more popular in modern plumbing installations. The popularity of toilet bowls of this type is due chiefly to the ease with which they permit a bathroom floor to be cleaned and to be carpeted or tiled as desired. Also, another factor contributing to the popularity of wall mounted toilet bowls is their modern and pleasing appearance. However, the art has been confronted with the problem of providing these bowls with means to make a satisfactory connection with soil pipes supported in the walls to which the wall mounted toilet bowls are attached.

It is a principal object of the present invention to pro vide a wall mounted toilet bowl having improved means for making a connection with a section of soil pipe.

It is a further object of the present invention to provide a wall mounted toilet bowl adapted to be secured to the wall of a building structure in substantial flush contact therewith for communication with a section of soil pipe, which section projects outwardly from the surface of the wall.

These and other objects and advantages of the present invention will become apparent from the following spec ification wherein like numerals refer to similar parts throughout.

In the drawings:

FIG. 1 is a perspective view of a wall mounted toilet bowl embodying the present invention; and

FIG. 2 is a partial elevation and a partial vertical section taken along the line 2-2 of FIG. 1 showing the wall mounted toilet bowl secured to the wall of a building structure.

FIG. 1 shows a wall mounted toilet bowl embodying the present invention, which toilet bowl has a flush tank 11 associated therewith. The toilet bowl is characterized by a vertically extending flat rear wall portion 12 which is adapted to be secured by cap nuts 13, or by other suitable means, to a building structure wall 14. The flat rear portion 12 includes a flat marginal surface which is just slightly spaced apart from the surface of the building structure wall 14 when the toilet bowl is secured thereto by the nuts 13 as best seen in FIG. 2. The distance between the surface 15 and the surface of the Wall 14 is determined by washers provided on the bolts engaged by the cap nuts 13. One of such washers, indicated at 16, is shown in FIG. 2. By this construction the toilet bowl is in substantially flush contact with the surface of the building wall. It is desirable to mount the flat rear portion 12 as closely as possible to the wall 14 to prevent the accumuation of dirt or other foreign matter therebetween and to provide a more secure mounting of the toilet bowl.

The flat rear portion 12 of the bowl 10 is provided with a circular cavity 17. The bowl 10 includes a waste or outlet conduit 18 extending rearwardly therein into the cavity 17 for co-axial communiaction with a horizontally disposed section of pipe, which is illustrated by the branch 19 of a sanitary T 20 housed within the wall 14. A flange 21 extends integrally from the branch 19, or the flange may be a separate member secured to the branch by any suitable means. The T 20 is joined to sections of soil pipe 22 and 23 which extend within the wall 14 and are part of the plumbing system of a building of which the wall 14 is a part.

It will be observed that the rear of the outlet conduit 18 is concentrically disposed within the circular cavity 17 thereby forming an annular chamber 24, which cham her is defined by the inside wall of the cavity 17 and the outside wall of the portion of the conduit 18 within the circular cavity 17. A sealing ring 25 is provided, and this ring is adapted to be received within the annular chamber 24 where it will be tightly engaged by the rim of the pipe flange 21 when the toilet bowl 10 is drawn against the wall 14 by the cap nuts 13, thereby forming a sealed joint between the outlet 18 and the soil pipe branch 19. It will be noted that the rear end of the conduit 18 terminates in the cavity 17 in a vertical plane which is inwardly offset from the marginal surface 15. By this construction it will be apparent that the toilet bowl of this invention is adapted to be securely mounted against the surface of a building wall with the flat rear portion thereof being substantially flush with the surface of the wall. And by the provision of the cavity 17 in the flat rear portion 12 having the rear end of the outlet conduit inwardly offset therein the outlet of the toilet bowl is adatped to communicate with a section of soil pipe mounted in the building wall, which section projects outwardly from the surface of the wall. This construction allows a more secure connection between the outlet conduit of the toilet bowl and the soil pipe in that the circular cavity acts as a seat for securely receiving a section of soil pipe. The annular chamber in the cavity also acts as an effective seat for the reception of the sealing ring which forms a seal with the flange of the soil pipe section to which the toilet bowl is connected. The circular cavity 17 formed in the flat rear portion 12 of the toilet bowl of this invention also acts as a centering means which assists in aligning the rear end of the outlet conduit 18 with the section of soil pipe, thereby providing for ease of installation of the toilet bowl.

The toilet bowl construction of this invention also includes another significant advantage. As is apparent from the above description, the toilet bowl is adapted to have the flat rear portion thereof mounted in substantial flush contact against the surface of the wall of a build ing structure for communication with a section of soil pipe, which section or branch projects outwardly from the surface of the wall. Because a section of soil pipe or the branch of a sanitary T is disposed exteriorly of the wall, the wall containing the drain pipe may be made substantially thinner. In fact, the Wall need only be thick enough to have the hollow portion thereof of a depth slightly in excess of the outside diameter of the soil pipe. Heretofore, when a known wall mounted toilet bowl was secured to the wall of a building structure, it was necessary to have the flange or end of the section of the soil pipe lying substantially in the plane of the surface of the wall to which the toilet bowl was attached if the bowl was to be mounted in flush contact with the wall since such a bowl did not have a cavity and inwardly offset outlet conduit for receiving a section of soil pipe. Manifestly, this requires the construction of a wall having a hollow portion with a depth substantially greater than the diameter of the soil pipe itself. Accordingly, it will be apparent that by the provision of the toilet bowl construction of this invention, substantial savings may be made in the cost of the walls of a building structure wherein such toilet bowls are used, and the size of the rooms in such a building will be increased.

Thus it will be seen that by this invention a wall mounted toilet bowl has been provided having improved means for connecting the outlet conduit therein with a section of soil pipe. The flat rear portion of the toilet bowl may be mounted substantially flush against the surface or the wall ina building structure over a pipe section which projects outwardly from the surface of the wall. Means are provided for effecting a sealed joint between the rear end of the bowl outlet conduit and the end of the section of pipe. Further, the toilet bowl of this invention is simple and inexpensive to construct.

While the invention has been shown in but one form it will be obvious to those skilled in the art that it is not to be so limited, but that it is susceptible of other changes and modifications without departing from the spirit and scope of the appended claims.

I claim:
